LOL. Normal. I did the exact same thing. My husband finally told me he was tired of shelling out money every time I had to pee. But I would take the test, see that positive sign, get excited...and then the next day, I'd think, "There's no way I have a baby in there." And off I'd go to the store to get another one. Shoot, I was too scared to cough hard - I was like, "What if it comes shooting out?"
You get over it. I promise.
But the first few weeks of a pregnancy seem to be a very fragile time...I was nervous as a cat, and could easily convince myself that I wasn't pregnant.
Hang in there, and give it a few weeks. And then you'll look back on your symptom-free days with nostalgia.
And congratulations on your pregnancy!!!
